Asbestos on Ships: The Hidden Danger That Still Claims Lives Today

Asbestos on ships is not a historical footnote — it is an ongoing occupational health crisis that continues to affect workers, veterans, and their families decades after the peak of its use. From the engine rooms of wartime destroyers to the cramped bilges of commercial vessels, asbestos was woven into the very fabric of maritime construction for the better part of the twentieth century.

Understanding where it was used, who was at risk, and what the law requires today is essential for anyone working in or around the maritime industry. The consequences of getting this wrong are severe — and irreversible.

Why Shipbuilders Relied So Heavily on Asbestos

Asbestos seemed like the perfect material for shipbuilding. It was cheap, abundant, and genuinely effective at resisting heat, fire, and electrical hazards — all critical concerns aboard a vessel at sea. From roughly the 1930s through to the 1970s, it was specified into almost every part of a ship’s construction.

Shipbuilders were not cutting corners — they were using the best available insulation technology of the era. The tragedy is that those same properties that made asbestos so attractive also made the fibres lethal when disturbed. The workers who built, maintained, and served aboard these vessels paid an enormous price for an industrial decision they had no say in.

Where Asbestos Was Used on Ships

Asbestos appeared throughout a vessel’s structure in numerous forms. On ships built before the mid-1970s, it is safer to assume asbestos is present than to assume it is not.

The most common applications included:

• Boiler and engine room insulation — lagging around boilers, turbines, and steam pipes was almost universally asbestos-based
• Electrical systems — wiring insulation and switchboard panels used asbestos to prevent fire propagation
• Bulkheads and deckheads — sprayed asbestos coatings and asbestos-containing board provided fire protection throughout accommodation and working areas
• Gaskets and seals — compressed asbestos fibre gaskets were standard components in pipe flanges and valves
• Brake linings — particularly on aircraft carriers where deck machinery required heavy-duty friction materials
• Fuel and exhaust systems — heat-resistant lagging on pipes and manifolds
• Floor tiles and adhesives — asbestos-containing vinyl tiles were common in accommodation areas

In practical terms, there was almost nowhere on a ship built before the mid-1970s where you could be confident asbestos was absent. Every compartment, every system, and every trade was affected.

The Particular Danger of Submarines and Below-Deck Spaces

If surface ships were bad, submarines were considerably worse. The confined geometry of a submarine meant that asbestos insulation was packed into spaces with almost no ventilation, leaving workers who installed, maintained, or repaired equipment with no choice but to breathe whatever was suspended in the air around them.

Below-deck spaces on all vessel types shared a similar problem. Poor air circulation meant that fibres disturbed during maintenance work did not dissipate — they remained suspended in the atmosphere for hours. A pipefitter working on a steam joint in a submarine’s machinery space was effectively working inside a cloud of asbestos dust for an entire shift.

This is why rates of asbestos-related disease among submariners and below-deck workers tend to be disproportionately high compared with other maritime trades. The exposure was not occasional — it was continuous, concentrated, and inescapable given the working conditions of the time.

The Health Consequences of Asbestos Exposure on Ships

The diseases caused by asbestos exposure are well-documented, serious, and in most cases incurable. What makes them particularly cruel is the latency period: symptoms typically do not emerge until 20 to 50 years after the initial exposure. Many workers who spent their careers in shipyards during the 1950s and 1960s only began developing illness in the 1990s and 2000s.

Mesothelioma

Mesothelioma is a cancer of the mesothelium — the lining that surrounds the lungs, abdomen, and heart. It is almost exclusively caused by asbestos exposure and carries a very poor prognosis, with median survival after diagnosis typically measured in months rather than years.

Shipyard workers and naval personnel are among the occupational groups with the highest historical rates of mesothelioma. The disease does not discriminate by trade — welders, electricians, laggers, and even administrative staff who worked near asbestos operations have all been affected.

Lung Cancer

Asbestos exposure significantly increases the risk of lung cancer, and that risk multiplies substantially for workers who also smoked. The interaction between asbestos fibres and tobacco smoke is not simply additive — it is synergistic, meaning the combined effect is far greater than either factor alone.

Shipyard workers who were both exposed to asbestos and were smokers faced a considerably elevated risk compared with the general population. Many of these individuals were entirely unaware of the compounding danger they faced.

Asbestosis

Asbestosis is a chronic fibrotic lung disease caused by the inhalation of asbestos fibres over time. The fibres embed in lung tissue and provoke an inflammatory response that leads to progressive scarring, reducing lung capacity and causing breathlessness that can eventually lead to respiratory failure.

Unlike mesothelioma, asbestosis is associated with higher cumulative exposures rather than single significant events. Workers who spent years in heavily contaminated environments — engine rooms, boiler spaces, submarine machinery compartments — were most at risk. There is no treatment that reverses the scarring.

Other Asbestos-Related Conditions

Beyond the three major diseases, asbestos exposure is associated with pleural plaques, pleural thickening, and pleural effusion. These conditions may not always cause significant symptoms but serve as markers of past exposure and can complicate breathing over time.

Who Was Affected — Including Families

The direct workforce in shipyards bore the heaviest burden of exposure, but they were far from the only people affected. The trades most at risk included:

• Laggers and insulators — who worked directly with asbestos materials
• Welders and burners — who cut through asbestos-lagged pipework and structures
• Pipefitters and plumbers — who disturbed asbestos when working on pipe systems
• Electricians — who worked in cable runs and switchrooms lined with asbestos board
• Boilermakers — who maintained and repaired heavily lagged equipment
• Shipwrights and carpenters — who cut and shaped asbestos-containing board

Secondary exposure was also a significant and often overlooked problem. Workers carried asbestos fibres home on their clothing, hair, and skin. Family members — particularly spouses who laundered work clothes — received meaningful doses of asbestos without ever setting foot in a shipyard.

Cases of mesothelioma in the wives and children of shipyard workers are well-documented in the medical literature. Beyond the home, workers in adjacent trades — security staff, canteen workers, and office personnel — who shared spaces with asbestos workers also faced elevated risks. Exposure did not require direct handling of the material.

The Regulatory Response: From Negligence to Legal Duty

For much of the period when asbestos use was at its peak, there was either no regulatory framework to protect workers or the existing rules were inadequate and poorly enforced. Medical researchers raised alarms about asbestos-related disease in shipyard workers during the 1960s, but industrial practice was slow to change.

In the UK, the regulatory landscape has evolved significantly. The Control of Asbestos Regulations now set out the legal duties for managing asbestos in workplaces, including vessels. The HSE’s guidance document HSG264 provides detailed practical guidance on asbestos surveys and the management of asbestos-containing materials.

These regulations apply not just to buildings but to any workplace — including ships undergoing refit, repair, or demolition. Ignorance of the rules is not a defence, and the penalties for non-compliance can be severe.

International Maritime Organisation Requirements

The International Maritime Organisation (IMO) has also taken action. Requirements now exist that new ships must be asbestos-free and that vessels undergoing significant work must have an Inventory of Hazardous Materials (IHM) documenting where asbestos is present before entering certain yards for repair or recycling.

The IHM requirement places formal responsibility on shipowners to know what hazardous materials their vessels contain. It represents a meaningful step forward in managing the legacy of asbestos on ships at an international level.

The Clemenceau Incident

The case of the French aircraft carrier Clemenceau illustrated just how seriously the international community had come to take asbestos on ships. When the vessel was sent to India for scrapping, campaigners raised serious concerns about the quantity of asbestos still aboard, and France was ultimately compelled to recall the ship for proper decontamination before scrapping could proceed.

The episode served as a high-profile reminder that the legacy of asbestos in the maritime fleet could not simply be exported away. Proper management and removal must happen regardless of where a vessel ends its operational life.

Asbestos on Ships Today: The Risk Has Not Gone Away

It would be a mistake to think of asbestos on ships as purely a historical problem. Any vessel built before the mid-1980s is likely to contain asbestos-containing materials somewhere in its structure. Many of these ships are still in service, still undergoing maintenance, and still capable of exposing workers to asbestos fibres if the materials are disturbed without proper controls.

Ship repair yards, dry docks, and naval maintenance facilities all need robust asbestos management procedures. Before any significant maintenance or refurbishment work begins on an older vessel, an asbestos survey must be carried out to identify and locate any asbestos-containing materials. This is not optional — it is a legal requirement under the Control of Asbestos Regulations.

Where asbestos is found, it must either be managed in place — if it is in good condition and not likely to be disturbed — or removed by a licensed contractor. Proper asbestos removal on ships presents particular challenges due to confined spaces, limited ventilation, and the complexity of the structures involved, all of which make specialist expertise absolutely essential.

Safe Removal and Management of Asbestos on Ships

When asbestos-containing materials on a vessel need to be removed or disturbed, the work must follow strict protocols. Cutting corners is not an option — the consequences for workers and the surrounding environment are too serious.

Key elements of safe asbestos management in a maritime context include:

1. Pre-work survey — a survey by a qualified surveyor to identify the type, location, and condition of all asbestos-containing materials before work begins
2. Licensed contractors — for most types of asbestos removal, particularly friable materials such as sprayed coatings and pipe lagging, a licensed contractor is legally required
3. Controlled work areas — enclosures with negative air pressure to prevent fibre migration beyond the work zone
4. Appropriate respiratory protective equipment — the correct grade of respirator for the type of work being undertaken
5. Air monitoring — continuous monitoring during removal to ensure fibre concentrations remain within acceptable limits
6. Correct waste disposal — double-bagged, clearly labelled, and disposed of at a licensed facility
7. Clearance inspection — a four-stage clearance procedure including a visual inspection and air testing before the area is returned to use

Each of these steps exists for a reason. Skipping any one of them creates a risk that can have consequences lasting decades — not just for the workers present, but for anyone who subsequently uses the space.

Practical Advice for Shipowners, Operators, and Maintenance Teams

If you own, operate, or maintain a vessel built before the mid-1980s, there are practical steps you should take now rather than waiting for a problem to emerge.

• Commission an asbestos survey if one has not been carried out recently. A management survey will identify the location and condition of any asbestos-containing materials and allow you to manage them safely. A refurbishment or demolition survey is required before any intrusive work begins.
• Maintain an asbestos register for the vessel. This document should record where asbestos is located, its type and condition, and the risk it presents. It must be made available to anyone who may disturb the material.
• Brief contractors before they start work. Anyone carrying out maintenance, repair, or refurbishment work on an older vessel must be told about any known asbestos-containing materials before they begin. This is a legal obligation, not a courtesy.
• Never assume a material is safe. If you are uncertain whether a material contains asbestos, treat it as though it does until a sample has been analysed by an accredited laboratory.
• Review your procedures regularly. Asbestos management is not a one-off exercise. Conditions change — materials deteriorate, vessels are modified, and new work creates new risks. Regular review keeps your management plan current.

For organisations operating across multiple locations, it is worth noting that the same legal duties apply whether your vessel is based on the Thames, the Mersey, or the Clyde. Businesses seeking an asbestos survey in London for vessels or maritime facilities in the capital can access specialist support locally, as can those needing an asbestos survey in Manchester or an asbestos survey in Birmingham for inland waterway or dock-adjacent properties.

The Legacy We Cannot Ignore

The story of asbestos on ships is, at its core, a story about what happens when industrial convenience is prioritised over worker safety — and about the decades-long consequences that follow. The workers who built Britain’s naval and merchant fleets during the mid-twentieth century had no meaningful choice about their exposure. Many of them, and members of their families, paid with their lives.

The regulatory framework that exists today — the Control of Asbestos Regulations, HSG264, and international maritime requirements — exists precisely because of that legacy. Compliance is not bureaucratic box-ticking. It is the minimum owed to everyone who will work on, in, or around these vessels going forward.

The responsibility now falls on shipowners, operators, maintenance managers, and contractors to ensure that the mistakes of the past are not repeated. That means surveying before working, managing what cannot be removed, and removing what must be removed — properly, legally, and safely.

Frequently Asked Questions

Is asbestos still found on ships in active service?

Yes. Any vessel built before the mid-1980s may contain asbestos-containing materials in its structure, insulation, or equipment. Many such ships remain in active service or are undergoing maintenance. Until a qualified surveyor has inspected the vessel and confirmed otherwise, it is safest to assume asbestos may be present in older ships.

What legal duties apply to asbestos on ships in the UK?

The Control of Asbestos Regulations apply to any workplace, including vessels undergoing repair, refit, or demolition. Shipowners and operators have a duty to manage asbestos-containing materials, commission appropriate surveys before intrusive work, and ensure that any removal is carried out by a licensed contractor. The HSE’s HSG264 guidance provides detailed practical support for meeting these obligations.

What is an Inventory of Hazardous Materials and do I need one?

An Inventory of Hazardous Materials (IHM) is a document required under International Maritime Organisation regulations for certain vessels. It records the location and quantity of hazardous materials — including asbestos — on board. It is required for new ships and for vessels entering yards for recycling or significant repair work. Shipowners should check whether their vessels fall within the scope of these requirements.

Can asbestos on a ship be managed in place rather than removed?

In some circumstances, yes. If asbestos-containing materials are in good condition, are not likely to be disturbed, and are properly documented and monitored, managing them in place may be appropriate. However, if materials are damaged, deteriorating, or located in areas where work will disturb them, removal by a licensed contractor is required. A qualified surveyor can advise on the correct approach for your specific vessel.

What should I do if I suspect asbestos has been disturbed on a vessel?

Stop work immediately and clear the area. Do not attempt to clean up any debris yourself. Notify your asbestos management team or a licensed contractor, and ensure that no one re-enters the affected space until it has been assessed and, if necessary, cleared by a competent person following the four-stage clearance procedure. Document the incident and report it in accordance with your asbestos management plan.

Asbestos in Ships: A Legacy of Danger That Still Affects Workers Today

For most of the twentieth century, asbestos was considered an engineering miracle. Cheap, lightweight, resistant to heat and fire, and seemingly indestructible — it was embraced by industries worldwide. Nowhere was it used more enthusiastically than in shipbuilding, and nowhere did it cause more devastation. Asbestos in ships affected hundreds of thousands of workers across the UK and beyond, leaving a trail of preventable illness that continues to this day.

Old vessels are still in service. Dry docks still handle aged hulls. Surveyors, engineers, and maintenance crews still encounter asbestos-containing materials on the water. This is not purely a historical problem — it is an active, ongoing risk that demands serious attention.

Why Shipbuilders Relied So Heavily on Asbestos

Ships are uniquely hostile environments. They carry enormous heat loads from boilers and engines, operate in saltwater that corrodes metal rapidly, and must meet stringent fire safety requirements. Asbestos addressed all of these problems in a single material, which is precisely why shipbuilders found it so appealing.

From the early twentieth century onwards, shipyards across Britain, the United States, and Europe incorporated asbestos into virtually every part of a vessel’s construction. It was woven into insulation, pressed into gaskets, mixed into paints, and sprayed directly onto structural steel. It appeared in sleeping quarters as well as engine rooms — no area of a ship was entirely free of it.

The scale of use was staggering. Asbestos-containing materials were found in well over 300 distinct ship components, including boilers, steam pipes, turbines, bulkheads, deckheads, cable runs, pump housings, and floor tiles.

The Role of Naval Specifications

Military navies accelerated the problem considerably. Naval specifications mandated asbestos use in many vessel types because of its fire-suppression properties. Once it became a regulatory requirement in military shipbuilding, commercial yards followed suit — and an entire industry built itself around a material that was already raising health concerns in other sectors.

British shipyards — particularly those on the Clyde, Tyne, Wear, and Mersey — were among the most productive in the world during this period. They were also among the most heavily contaminated workplaces in the country.

Common Asbestos-Containing Materials Found in Ships

The variety of asbestos-containing materials (ACMs) used in shipbuilding is one of the reasons the industry produced such high rates of asbestos-related disease. Workers were not dealing with a single product in a single location — they were surrounded by asbestos in dozens of different forms throughout every working day.

Typical ACMs found in ships include:

• Pipe lagging and thermal insulation — applied to steam pipes, boiler casings, and exhaust systems throughout the vessel
• Sprayed asbestos coatings — applied directly to structural steel for fire protection and thermal management
• Asbestos cement panels and boards — used in bulkheads, deckheads, and accommodation areas
• Gaskets and packing materials — used to seal pipe joints, valves, and flanges throughout engineering spaces
• Insulating rope and tape — wrapped around pipes and cable runs
• Floor tiles and deck coverings — particularly in high-traffic areas and accommodation
• Asbestos-reinforced paints and coatings — applied to internal walls, decks, and machinery
• Electrical cable insulation — asbestos was used as a fire-resistant sheath on wiring throughout the ship
• Textiles and blankets — used in sleeping quarters and as protective coverings for hot surfaces
• Pump and valve components — asbestos was incorporated into seals and internal components designed to handle high-pressure steam

Each of these materials presented its own exposure risk, depending on whether it was being installed, maintained, repaired, or removed. The more friable the material, the greater the risk of airborne fibre release.

Asbestos Exposure in UK Shipyards: The Scale of the Problem

British shipyards were at the peak of their output from the 1930s through to the 1970s — precisely the period when asbestos use was most intensive. Workers in these yards faced daily exposure to asbestos fibres in conditions that would be completely unacceptable today.

Ventilation in ship interiors was poor. Workers cutting, fitting, and removing insulation in confined spaces below deck were effectively breathing concentrated asbestos dust for entire shifts. There were no adequate respirators, no dust suppression measures, and — critically — no meaningful communication to workers about the risks they were taking.

The consequences have been catastrophic. Mesothelioma, lung cancer, asbestosis, and pleural disease have claimed the lives of thousands of former shipyard workers across the UK. Because asbestos-related diseases typically have a latency period of between 20 and 60 years, many workers exposed in the 1950s and 1960s did not receive a diagnosis until the 1990s or later — often decades after they had retired.

The Occupations Most at Risk

Whilst all shipyard workers faced some level of exposure, certain trades were at far greater risk due to the nature of their daily tasks.

Insulators faced the most severe exposure of any shipyard trade. Their entire job involved handling, cutting, and fitting asbestos insulation around pipes, boilers, and machinery. Working in tight spaces with poor ventilation, insulators routinely generated clouds of airborne asbestos fibre.

Welders and burners were frequently required to cut through existing asbestos insulation to access pipework or structural steel. The combination of heat and mechanical disturbance released fibres into the air, and the confined spaces in which much of this work took place meant exposure levels were extremely high.

Pipefitters and plumbers worked constantly alongside asbestos-lagged pipework. Fitting new pipe sections, removing old lagging, and working on steam systems brought them into direct contact with friable asbestos materials on a daily basis.

Joiners and carpenters cutting asbestos insulating board for bulkheads and accommodation areas were also heavily exposed, as were painters applying asbestos-containing coatings and labourers who swept up asbestos debris at the end of shifts.

Health Consequences of Asbestos in Ships

The diseases caused by asbestos exposure in the shipbuilding industry are severe, progressive, and in most cases fatal. There is no safe level of asbestos exposure, and even relatively brief contact with asbestos fibres can trigger disease decades later.

Mesothelioma

Mesothelioma is a cancer of the lining of the lungs, abdomen, or heart. It is almost exclusively caused by asbestos exposure and has no cure. The prognosis is extremely poor, with most patients surviving less than two years after diagnosis. Shipyard workers have historically been among the most affected occupational groups.

Lung Cancer

Asbestos is a recognised cause of lung cancer, and the risk is significantly elevated in shipyard workers who were also smokers. The combination of tobacco and asbestos exposure multiplies lung cancer risk considerably beyond either factor alone.

Asbestosis

Asbestosis is a chronic scarring of lung tissue caused by the inhalation of asbestos fibres over time. It causes progressive breathlessness, reduced lung capacity, and a persistent cough. There is no treatment that reverses the scarring, and the condition worsens over time even after exposure has ended.

Pleural Disease

Pleural plaques, pleural thickening, and pleural effusions are all associated with asbestos exposure. Whilst pleural plaques themselves are not cancerous, they indicate significant past exposure and are associated with an increased risk of more serious asbestos-related conditions.

Many former shipyard workers also develop cancers of the larynx, stomach, and colon that are linked to asbestos exposure — connections that are sometimes less widely recognised than the primary respiratory diseases.

Legal Recourse for Former Shipyard Workers

The legal history of asbestos in shipbuilding is long and significant. Employers and asbestos product manufacturers knew — or should have known — about the dangers of asbestos long before they took meaningful action to protect workers. This knowledge, combined with documented evidence of inadequate safety measures, has formed the basis of thousands of successful legal claims.

Former shipyard workers, their families, and the dependants of those who have died from asbestos-related disease may be entitled to compensation through:

1. Civil claims against former employers — where negligence in providing adequate protection can be demonstrated
2. Claims against asbestos product manufacturers — where the products supplied were defective or inadequately labelled
3. Industrial Injuries Disablement Benefit — a government scheme for workers diagnosed with prescribed industrial diseases including mesothelioma and asbestosis
4. The Diffuse Mesothelioma Payment Scheme — for those unable to trace a former employer or their insurer

Legal cases involving shipyard workers have resulted in substantial settlements. Families of workers who died from diseases contracted in the yards have successfully pursued claims many years after their loved ones’ deaths. Specialist solicitors with experience in industrial disease claims are the right starting point for anyone affected.

Asbestos in Ships Today: The Ongoing Risk

A significant proportion of vessels currently in service worldwide were built before asbestos use was restricted or banned. Many of these ships still contain large quantities of asbestos-containing materials, particularly in areas that have not been refurbished or stripped.

Ship recycling — the process of breaking down old vessels at the end of their working lives — is a major source of ongoing asbestos exposure risk. Shipbreaking yards, many of which operate in South Asia, handle vessels containing substantial quantities of asbestos with limited protective measures, creating serious occupational health problems in those regions.

In the UK, the Control of Asbestos Regulations impose strict duties on those who manage, maintain, or work on vessels containing asbestos. The regulations require that asbestos-containing materials are identified, assessed, and managed appropriately. Where work is likely to disturb ACMs, a licensed contractor must be engaged and appropriate controls must be in place before work begins.

The Duty to Manage Asbestos on Vessels

The duty to manage asbestos applies to vessels just as it does to buildings. Owners and operators of ships built before the ban on asbestos use came into effect must ensure that a suitable asbestos register is in place, that the condition of known ACMs is regularly reviewed, and that anyone working on the vessel is made aware of the location and condition of asbestos-containing materials.

Failure to manage asbestos appropriately on a vessel is a criminal offence under the Control of Asbestos Regulations and can result in substantial fines as well as civil liability if workers are harmed.

What Type of Asbestos Survey Do You Need?

If you manage a vessel, a dry dock facility, a marine engineering workshop, or any property connected to the maritime industry, a professional asbestos survey is the essential first step in understanding your risk. This applies equally to onshore infrastructure as it does to the vessels themselves.

There are two primary survey types relevant to maritime and industrial settings:

Management Survey

A management survey is required for any premises or vessel in normal occupation and use. It identifies the location, type, and condition of asbestos-containing materials so that a management plan can be put in place. This is the baseline requirement for any duty holder.

Refurbishment and Demolition Survey

Where a vessel or associated property is undergoing significant repair, refurbishment, or decommissioning, a refurbishment survey is required before any intrusive work begins. This survey is more invasive than a management survey — it involves destructive inspection to locate all ACMs that could be disturbed during the planned works.

For vessels undergoing major overhaul, dry dock work, or end-of-life processing, a refurbishment and demolition survey is not optional. It is a legal requirement, and proceeding without one puts workers at serious risk and exposes the duty holder to criminal liability.

Frequently Asked Questions

Is asbestos still found in ships that are currently in service?

Yes. Many vessels built before asbestos use was restricted or banned still contain asbestos-containing materials, particularly in areas that have not been refurbished. Engine rooms, boiler spaces, pipe runs, and accommodation areas are all common locations. Any vessel of a certain age should be treated as potentially containing asbestos until a survey confirms otherwise.

Who is responsible for managing asbestos on a vessel?

The duty to manage asbestos falls on the owner or operator of the vessel — whoever has responsibility for its maintenance and the safety of those working on it. Under the Control of Asbestos Regulations, duty holders must ensure that ACMs are identified, their condition is monitored, and that workers are informed of any asbestos present. Failure to do so is a criminal offence.

What should happen before refurbishment or repair work on an older vessel?

Before any intrusive work begins on a vessel that may contain asbestos, a refurbishment and demolition survey must be carried out by a qualified surveyor. This identifies all ACMs that could be disturbed during the planned works. Licensed asbestos removal contractors must then remove any relevant materials before other trades begin work. Skipping this step is both illegal and extremely dangerous.

Can former shipyard workers still make a legal claim for asbestos-related illness?

Yes, in many cases they can. Claims can be made against former employers, asbestos product manufacturers, or through government compensation schemes such as the Diffuse Mesothelioma Payment Scheme. Legal time limits do apply, so anyone affected should seek specialist legal advice as soon as possible. Solicitors experienced in industrial disease claims are best placed to advise on the options available.

What types of asbestos were most commonly used in shipbuilding?

All three main commercial types of asbestos — crocidolite (blue), amosite (brown), and chrysotile (white) — were used in shipbuilding. Crocidolite and amosite are considered the most hazardous and were widely used in thermal insulation and pipe lagging. Chrysotile appeared in gaskets, textiles, and cement products. All three types are capable of causing mesothelioma, lung cancer, and asbestosis.

Asbestos Exposure in Shipyards: What UK Site Managers Still Need to Know

For decades, asbestos exposure in shipyards was treated as an occupational norm. It sat behind pipe lagging, inside engine rooms, around boilers, within sprayed coatings and insulation boards, and in countless repair materials used every day. Workers rarely saw the danger coming. Once asbestos fibres were disturbed, they became airborne and could be inhaled deep into the lungs — often without any immediate warning signs.

That legacy has not gone away. Although asbestos is banned in the UK, many older vessels, dockside buildings, workshops and plant rooms still contain asbestos-containing materials (ACMs). If you manage a port facility, marine engineering site, ship repair operation or former shipbuilding premises, understanding where asbestos may be present and how to control the risk is not optional — it is a legal duty.

Why Asbestos Exposure in Shipyards Was So Widespread

Shipbuilding and ship repair demanded materials that could cope with heat, fire, vibration, moisture and salt-heavy conditions. Asbestos ticked every one of those boxes, which is why it became so deeply embedded across the maritime sector.

It was added to products for insulation, fire protection, sealing and durability. In practical terms, that meant asbestos appeared in areas where workers cut, drilled, stripped, removed, repaired and cleaned on a daily basis. The material was everywhere — and so was the risk.

Common Asbestos-Containing Materials Found in Shipyards and on Vessels

Asbestos was used in a wide range of products on ships and throughout shipyard infrastructure. Many of these materials are still discovered during refurbishment, maintenance or demolition work today.

• Pipe and boiler insulation
• Thermal lagging in engine rooms
• Sprayed coatings for fire protection
• Asbestos insulating board (AIB)
• Cement panels and sheets
• Gaskets, seals and rope packing
• Floor tiles and bitumen adhesives
• Textured coatings and mastics
• Electrical flash guards and cable insulation
• Brake linings and friction materials
• Doors, panels and bulkhead linings
• Paints, coatings and compounds used in older marine environments

In shipyards, asbestos was not limited to the vessel itself. Workshops, stores, offices, dry docks, pump houses and plant rooms may all contain asbestos within the building fabric or service systems. Never assume the risk stops at the waterline.

Where Asbestos Exposure in Shipyards Happened Most Often

Asbestos exposure in shipyards was rarely confined to a single trade. Anyone working near disturbed materials could inhale fibres, even if asbestos handling was not part of their role. The highest-risk situations involved maintenance, stripping-out, refitting and demolition — tasks that damaged ACMs and released fibres into enclosed or poorly ventilated spaces.

High-Risk Shipyard Roles

• Laggers and insulators
• Boilermakers
• Welders and burners
• Pipefitters and plumbers
• Electricians
• Joiners and carpenters
• Engineers and fitters
• Maintenance teams
• Demolition and salvage workers
• Cleaners working in contaminated areas
• Naval and merchant vessel repair crews

Tasks That Created the Greatest Risk

• Removing old lagging from pipes and boilers
• Cutting or drilling asbestos insulating board
• Breaking out damaged insulation during repairs
• Stripping engine rooms and plant spaces
• Sweeping dust and debris without proper controls
• Refitting older ships without a suitable asbestos survey
• Demolishing marine structures or decommissioning vessels

Confined spaces made the problem significantly worse. Fibre release in engine rooms, duct runs and service voids could build up rapidly if work was uncontrolled. Poor ventilation meant concentrations could reach dangerous levels before anyone realised what was happening.

The Health Risks Linked to Asbestos Exposure in Shipyards

The danger with asbestos is not immediate irritation. The main health effects often appear many years — sometimes decades — after exposure, which is one reason so many former shipyard workers were diagnosed long after leaving the industry. Even relatively short periods of intense exposure can be significant. Repeated lower-level exposure over time can also cause serious, life-limiting disease.

Mesothelioma

Mesothelioma is a cancer directly associated with asbestos exposure. It affects the lining of the lungs or, less commonly, the lining of the abdomen. There is no safe threshold for dismissing possible past exposure, especially where work involved insulation, boiler rooms or stripping-out older vessels.

Symptoms can include chest pain, breathlessness and persistent fatigue. Anyone with a history of shipyard asbestos exposure should inform their GP about that occupational background without delay.

Lung Cancer

Asbestos can cause lung cancer independently of other risk factors. The risk is compounded for people who have both asbestos exposure and a history of smoking, but asbestos alone remains a serious hazard. Persistent cough, unexplained weight loss, chest pain or breathlessness should always be investigated promptly — these symptoms should never be dismissed as minor.

Asbestosis and Other Non-Malignant Conditions

Asbestosis is scarring of the lung tissue caused by inhaling asbestos fibres over time. It can lead to long-term breathing difficulty and significantly reduced lung function. Other asbestos-related conditions include pleural thickening and pleural plaques.

These may not always be cancerous, but they do indicate past exposure and can meaningfully affect quality of life. They may also increase the risk of developing more serious conditions later.

Why the Risk Still Exists Today

Many people assume asbestos in shipyards is purely a historical concern. It is not. The use of asbestos has been banned, but older ships, dock buildings and industrial units can still contain it in significant quantities. If those materials remain in good condition and are properly managed, the risk can often be controlled effectively.

The problem starts when materials are damaged, deteriorate with age, or are disturbed during maintenance, refurbishment or demolition without adequate preparation. That is why dutyholders need a clear asbestos management plan backed by reliable survey information. Guesswork is where exposure incidents happen.

Common Modern Scenarios That Still Lead to Exposure

• Refurbishment of older dockside workshops
• Repair work on legacy vessels
• Removal of old pipework or plant
• Roofing and cladding replacement in marine industrial buildings
• Intrusive electrical or mechanical upgrades
• Demolition of former shipbuilding premises

If your site includes older buildings in the capital, arranging an asbestos survey London before works begin is a practical and legally sound first step. The same principle applies across every major port and industrial area in the UK.

What UK Law Requires from Shipyard Owners, Employers and Dutyholders

The legal framework is unambiguous. Under the Control of Asbestos Regulations, those responsible for non-domestic premises must identify asbestos risks and manage them properly. In marine settings, that can include workshops, warehouses, offices, dry dock facilities and other operational buildings.

Survey work should follow HSG264, which sets out how asbestos surveys must be carried out. Wider compliance should align with relevant HSE guidance on identification, management, licensed work, training and control measures.

In practical terms, dutyholders should:

1. Find out whether asbestos is present in their premises
2. Assess the condition of any asbestos-containing materials
3. Keep an up-to-date asbestos register
4. Make that information available to anyone who may disturb the material
5. Review and monitor the condition of asbestos at regular intervals
6. Arrange the correct survey type before any refurbishment or demolition work

If work is planned and the asbestos information is incomplete, stop and verify the risk first. Starting intrusive works without suitable asbestos information is one of the most common — and most preventable — compliance failures in the industry.

Management Surveys and Refurbishment Surveys in Shipyard Settings

Not every survey serves the same purpose. Choosing the right one matters because the scope, level of intrusion and intended use differ significantly between survey types.

Management Survey

A management survey is used to locate, as far as reasonably practicable, the presence and condition of asbestos-containing materials that could be disturbed during normal occupation, routine maintenance or foreseeable use. This is the baseline survey for any occupied premises.

For shipyard support buildings and operational spaces, it helps you build an asbestos register and management plan. It is the starting point — not the end of the process.

Refurbishment Survey

Where intrusive work is planned, a refurbishment survey is typically required. This is a fully intrusive survey designed to locate asbestos in the area of planned works, including materials that are concealed behind linings, above ceilings, inside risers or around plant.

That is especially relevant in older marine buildings where asbestos may be hidden beneath layers of later finishes. If you are preparing works in the North West, booking an asbestos survey Manchester team before strip-out or upgrade works can prevent delays, exposure incidents and costly project stoppages.

Demolition Survey

For full demolition of a structure, a demolition survey is required. This is the most thorough survey type and must be completed before any demolition work begins. It is designed to locate all asbestos-containing materials in the structure, regardless of condition or location.

Former shipbuilding premises being cleared for redevelopment frequently contain asbestos in unexpected locations. A demolition survey ensures no material is missed before contractors move in.

How to Reduce Asbestos Risk in Active and Former Shipyards

Managing asbestos risk is not complicated when the process is structured properly. Problems arise when sites rely on assumptions, outdated records or informal contractor knowledge passed down through word of mouth.

Use a clear, structured control approach:

1. Identify likely ACMs through records, inspection and appropriate survey work
2. Assess the material condition and the likelihood of disturbance
3. Record findings in an asbestos register that is easy to access and regularly updated
4. Communicate the information to staff, contractors and maintenance teams before work begins
5. Control the work using permits, isolation, suitable methods and competent contractors
6. Review the condition of known materials at planned intervals and after any disturbance

Practical Actions for Property and Facilities Managers

• Check whether your asbestos register is current and site-specific — generic registers are not sufficient
• Match the survey type to the planned work, not just the age of the building
• Brief contractors before they start, not after they discover suspect materials
• Label or otherwise clearly identify known ACMs where appropriate
• Prevent ad hoc drilling, cutting or access into hidden voids without prior checks
• Escalate damaged materials immediately for professional inspection
• Keep records of reinspections, removals and sample results in a centralised log

Where larger industrial estates or legacy marine sites are being redeveloped in the Midlands, an asbestos survey Birmingham appointment can help establish a compliant starting point before contractors move in.

What to Do If Asbestos Is Suspected on a Shipyard Site

If someone uncovers a suspect material during work, the right response is to stop before the situation becomes an exposure incident. Do not attempt to break, sample or remove the material without the correct controls in place.

Take these steps immediately:

1. Stop work in the immediate area
2. Keep people away and prevent further disturbance
3. Isolate the area if safely possible
4. Report the issue to the site manager or dutyholder
5. Arrange inspection and sampling by a competent asbestos professional
6. Review whether the planned works require a refurbishment or demolition survey before continuing

Do not rely on visual judgement alone. Many ACMs look similar to non-asbestos products, and some of the most hazardous materials are hidden beneath later finishes. Only laboratory analysis of a properly taken sample can confirm whether asbestos is present.

Training, Communication and Contractor Control

Training is one of the most effective ways to reduce asbestos exposure in shipyards and similar industrial settings. Anyone liable to disturb asbestos during their work should have appropriate asbestos awareness training. That includes maintenance teams, engineers, electricians, plumbers and general trades working in older premises.

Awareness training does not qualify someone to remove asbestos. It helps them recognise likely materials, understand the risks involved and know when to stop and seek expert advice before proceeding.

Good contractor controls should include:

• Pre-start asbestos information packs covering known ACMs on site
• Permit-to-work systems for any intrusive tasks
• Clear site inductions covering asbestos locations and emergency procedures
• Checks that survey information matches the specific work area
• Escalation procedures for suspect materials discovered during work
• Use of licensed contractors where the work legally requires it

On complex sites, this level of control can prevent one poor decision from contaminating a large work area and triggering a costly remediation programme.

Asbestos Removal, Remediation and Ongoing Management

Finding asbestos does not automatically mean it must be removed immediately. If the material is in good condition and is unlikely to be disturbed, management in situ may be the appropriate course of action under the Control of Asbestos Regulations.

Removal becomes necessary where materials are damaged, friable, in the path of planned works, or where the risk of disturbance cannot be adequately controlled through management alone. In those cases, asbestos removal by a licensed contractor is required.

After removal, a four-stage clearance procedure should be followed before the area is reoccupied. This includes a thorough visual inspection and air testing carried out by an independent analyst — not the contractor who performed the removal work.

Ongoing management means keeping the asbestos register updated, scheduling periodic reinspections of known ACMs, and ensuring that any changes to the site or planned works trigger a review of the asbestos information before work begins.

Frequently Asked Questions

Is asbestos still found in UK shipyards and dockside buildings?

Yes. Although the use of asbestos has been banned in the UK, many older vessels, dockside buildings, workshops, plant rooms and marine industrial structures still contain asbestos-containing materials. The risk is particularly relevant in buildings and vessels constructed or refurbished before the ban came into force. Any site with older infrastructure should have a current asbestos survey and management plan in place.

What type of asbestos survey is needed before shipyard refurbishment work?

For planned refurbishment or intrusive maintenance, a refurbishment survey is required. This is a fully intrusive survey carried out in the specific area of planned works. It is designed to locate all ACMs, including those concealed behind linings, above suspended ceilings or within service voids. A management survey alone is not sufficient before intrusive work begins. For full demolition, a demolition survey is required instead.

Who is legally responsible for managing asbestos in a shipyard or port facility?

Under the Control of Asbestos Regulations, the dutyholder — typically the owner or person in control of the premises — is responsible for managing asbestos risk in non-domestic buildings. This includes identifying whether asbestos is present, assessing its condition, maintaining an asbestos register and ensuring that anyone who may disturb the material is given appropriate information before starting work.

What health conditions are associated with asbestos exposure in shipyards?

The main asbestos-related diseases are mesothelioma, lung cancer, asbestosis, pleural thickening and pleural plaques. These conditions typically develop many years after exposure, which is why former shipyard workers may receive a diagnosis long after leaving the industry. Anyone with a history of working in shipyards or marine environments should inform their GP about that occupational history, particularly if they develop respiratory symptoms.

Does all asbestos in a shipyard building need to be removed?

Not necessarily. Under UK regulations, if asbestos-containing materials are in good condition and are unlikely to be disturbed, it may be appropriate to manage them in situ rather than remove them. However, where materials are damaged, deteriorating or in the path of planned works, removal by a licensed contractor will be required. A professional asbestos survey will identify which materials need to be removed and which can be safely managed.

Ships, Asbestos, and a Legacy That Still Haunts Britain’s Waterfronts

Ships once carried a deadly secret hidden within their hulls, engine rooms, and sleeping quarters. The history of asbestos use in shipbuilding and its consequences is one of the most sobering industrial stories of the twentieth century — a miracle material that became a mass killer, leaving a trail of disease, litigation, and grief that continues to this day.

From the Clyde to the Tyne, from Belfast’s Harland and Wolff to the great naval yards of Portsmouth and Devonport, British shipbuilding was built on asbestos. Understanding how this happened — and what it cost — matters enormously, not just historically, but because the legacy of that contamination still lives inside ageing vessels, dry docks, and waterfront buildings across the UK.

Why Shipbuilders Turned to Asbestos

In the early decades of the twentieth century, shipbuilders faced a pressing and very real problem: fire. A blaze below deck on a steel-hulled vessel is catastrophic, and the materials available to combat it were limited. Asbestos appeared to be the perfect solution.

It was naturally fireproof, capable of withstanding extreme temperatures without burning or melting. It was also lightweight, cheap to source, and extraordinarily versatile — it could be woven into lagging, compressed into boards, mixed into cement, or sprayed directly onto steel structures. For naval engineers and commercial shipbuilders alike, it ticked every box.

Asbestos found its way into virtually every part of a vessel:

• Engine rooms and boiler spaces, where heat management was critical
• Pipe lagging throughout the ship’s infrastructure
• Bulkheads and partition walls between compartments
• Sleeping quarters and crew accommodation areas
• Flooring tiles and ceiling panels
• Gaskets, rope seals, and mechanical fittings

The material’s durability in harsh maritime conditions — salt air, constant vibration, extreme humidity — made it even more appealing. What nobody adequately considered was what happened when those fibres became airborne.

Wartime Shipbuilding and the Asbestos Surge

The Second World War accelerated asbestos use in shipbuilding to an extraordinary degree. Both the Allied navies and commercial shipping operators needed vessels built quickly, in vast numbers, and to exacting fire-safety standards. Asbestos was the answer to all three demands simultaneously.

In British yards, production was relentless. Harland and Wolff in Belfast, Cammell Laird on Merseyside, and yards along the Tyne and Clyde worked around the clock. Asbestos lagging was applied to pipes, boilers, and bulkheads at a furious pace. Workers — many of them young men with no prior experience of industrial hazards — handled raw asbestos materials in confined, poorly ventilated spaces with no protective equipment whatsoever.

The urgency of wartime production meant that any concerns about worker health — and there were some, even then — were firmly suppressed. Getting ships into the water was the only priority. The consequences of that decision would take decades to fully emerge.

The Post-War Years: Asbestos Use Continues Unchecked

When the war ended, the shipbuilding industry did not abandon asbestos. If anything, its use expanded into commercial shipbuilding on a massive scale throughout the 1950s and 1960s. Passenger liners, cargo vessels, tankers, and ferries were all built using the same asbestos-heavy construction methods developed during wartime.

The Cold War kept naval shipbuilding at high levels, and military specifications continued to mandate asbestos throughout submarines and surface warships. It remained cheap, effective, and — crucially — still not widely understood by the workforce to be dangerous.

There was, however, a growing body of medical evidence that should have prompted action far sooner. Studies linking asbestos dust to serious lung disease had begun appearing in medical literature from as early as the 1930s. Some manufacturers and employers were aware of these findings. The decision to withhold that information from workers would later become the basis for some of the largest industrial compensation claims in legal history.

The History of Asbestos Use in Shipbuilding and Its Consequences: The Health Toll

The cruel characteristic of asbestos-related disease is its latency. When asbestos fibres are inhaled, they lodge deep within lung tissue and the pleural lining — and they stay there. The body cannot break them down. Over the course of decades, those fibres cause progressive scarring, inflammation, and cellular damage that eventually manifests as serious, often fatal, disease.

For shipyard workers who handled asbestos in the 1940s, 1950s, and 1960s, the diagnoses began arriving in the 1980s, 1990s, and beyond. Connecting a terminal cancer diagnosis to work done forty years earlier was not straightforward — and that delay was exploited by employers and insurers for years.

Mesothelioma

Mesothelioma is a cancer of the mesothelial lining — most commonly the pleura surrounding the lungs, though it can also affect the peritoneum and pericardium. It is almost exclusively caused by asbestos exposure and carries an extremely poor prognosis. Most patients survive less than two years from diagnosis.

Shipyard workers are among the occupational groups most heavily represented in mesothelioma statistics. Towns like Barrow-in-Furness, Birkenhead, and Govan have historically recorded some of the highest mesothelioma rates in the country, directly traceable to their shipbuilding heritage.

Asbestosis

Asbestosis is a chronic, progressive scarring of the lung tissue caused by prolonged asbestos exposure. It causes breathlessness, a persistent cough, and eventually severe respiratory failure. It is not cancer, but it is debilitating and incurable.

Shipyard workers who spent years in enclosed spaces cutting, fitting, and removing asbestos lagging were at particularly high risk. The disease often did not manifest until many years after the original exposure had ended.

Lung Cancer

Asbestos exposure significantly increases the risk of lung cancer, particularly in those who also smoked. The combination of tobacco and asbestos fibres creates a multiplicative risk — far greater than either factor alone. Many shipyard workers of the wartime and post-war generations were also smokers, which compounded their already serious occupational exposure.

Pleural Disease

Even lower levels of asbestos exposure can cause pleural plaques — areas of fibrous thickening on the pleural lining. These are not cancerous, but they are a marker of exposure and can cause discomfort and breathlessness. Diffuse pleural thickening is a more serious condition that can significantly impair lung function over time.

The Legal Fallout: Compensation, Litigation, and Accountability

As the true scale of asbestos-related disease in shipbuilding communities became undeniable, the legal consequences for employers, manufacturers, and insurers were enormous. Workers and their families began bringing claims against shipyard operators and asbestos product manufacturers — and in many cases, they succeeded.

Landmark cases in the UK established that employers had known, or ought to have known, about the dangers of asbestos exposure well before they took meaningful action to protect workers. Compensation awards ran into millions of pounds for individual claimants, and the financial impact on the asbestos industry and shipyard operators was catastrophic. Numerous companies went bankrupt under the weight of claims.

Insurance funds were established specifically to handle the volume of asbestos-related claims, and some are still paying out today. The litigation was not confined to the UK — in the United States, the Veterans Administration introduced specific benefits for veterans who had developed asbestos-related disease through their service, an acknowledgement that the military’s reliance on asbestos had directly caused the illness of thousands of servicemen and women.

For families of those affected, the legal process was rarely straightforward. Proving exposure, identifying liable parties, and navigating insurers who had gone out of business decades earlier created enormous barriers. Many claimants died before their cases were resolved.

How UK Regulation Responded to the Asbestos Crisis

The UK’s regulatory response to the asbestos crisis in shipbuilding was gradual but ultimately decisive. The Control of Asbestos Regulations brought together decades of evolving legislation into a single framework that governs how asbestos must be managed, surveyed, and removed across the UK today.

These regulations place clear duties on employers and building owners — including those responsible for vessels, dry docks, and maritime facilities — to identify asbestos-containing materials, assess their condition, and manage the risk they pose. Failure to comply is a criminal offence, not merely a civil liability.

The HSE’s guidance document HSG264 sets out the standards that asbestos surveys must meet, distinguishing between management surveys for ongoing use and refurbishment and demolition surveys for more intrusive work. Critically, the regulations do not only apply to buildings. Any structure, vessel, or facility where people work and where asbestos may be present falls within scope.

For the maritime sector, this means that historic vessels, working boats, and port facilities all require proper asbestos management. A professional management survey is the appropriate starting point for any duty holder seeking to understand what asbestos-containing materials are present and what condition they are in.

Where refurbishment or demolition work is planned, a demolition survey is required to locate all asbestos before work begins — protecting both workers and the public.

Secondary Exposure: When Asbestos Followed Workers Home

One of the most heartbreaking dimensions of the history of asbestos use in shipbuilding and its consequences is the phenomenon of secondary, or para-occupational, exposure. Shipyard workers did not leave asbestos behind when they clocked off. Fibres clung to their overalls, hair, and skin, and were carried home on public transport and into family homes.

Wives, children, and other household members who shook out or washed those contaminated work clothes were exposed to asbestos fibres without ever setting foot inside a shipyard. Decades later, some of those family members received their own diagnoses of mesothelioma or asbestosis — diseases they contracted entirely through proximity to someone else’s working life.

This secondary exposure remains one of the most legally and morally complex aspects of the asbestos legacy. It demonstrates, with painful clarity, that the consequences of industrial decisions do not stay within the factory gates.

The Ongoing Legacy in Britain’s Maritime Communities

The history of asbestos use in shipbuilding and its consequences did not end when the yards fell silent. Communities built around shipbuilding — from the banks of the Mersey to the docks of Glasgow — continue to live with the health legacy of asbestos exposure. Mesothelioma diagnoses are still being made in men who worked in shipyards decades ago.

Britain’s remaining historic vessels also present a practical challenge. Many older ships, barges, and working boats that are still in service or preserved as heritage vessels contain asbestos-containing materials in their original fabric. Owners and operators have a legal duty to manage this risk, and anyone carrying out maintenance, refurbishment, or restoration work on such vessels needs a clear understanding of what they may be dealing with.

Waterfront Properties and Dockside Buildings

The legacy of shipbuilding extends beyond the vessels themselves. Dockside warehouses, engine sheds, administrative buildings, and workshops built during the peak years of shipbuilding activity frequently contain asbestos in their fabric. Many of these buildings have since been converted into residential, commercial, or leisure use — often without adequate asbestos assessment.

If you are responsible for a maritime facility, a historic vessel, or a waterfront property, professional asbestos surveying is not optional. It is a legal requirement and, given the history, a moral one.

For those managing dockside or waterfront properties in the capital, a professional asbestos survey London will identify any remaining asbestos-containing materials and ensure you meet your obligations under the Control of Asbestos Regulations.

In the north-west, where the shipbuilding heritage of the Mersey runs deep, an asbestos survey Manchester can help property managers and building owners understand exactly what they are dealing with — and how to manage it safely and legally.

In the West Midlands, where industrial heritage buildings are increasingly being repurposed, an asbestos survey Birmingham provides the same rigorous assessment, carried out by qualified surveyors who understand the built environment and the regulations that govern it.

What Duty Holders Must Do Now

The history of asbestos in shipbuilding is not merely a historical curiosity. It has direct, practical implications for anyone who owns, manages, or is responsible for buildings, vessels, or facilities with connections to Britain’s maritime past. Here is what the law requires — and what good practice demands:

1. Identify whether asbestos is present. If your property or vessel was built or significantly refurbished before the year 2000, asbestos-containing materials may be present. Do not assume otherwise.
2. Commission a professional survey. Only a qualified asbestos surveyor can carry out an assessment that meets HSG264 standards. Do not rely on visual inspections or informal assessments.
3. Produce and maintain an asbestos register. Once asbestos-containing materials are identified, their location, condition, and risk level must be recorded and kept up to date.
4. Implement a management plan. The Control of Asbestos Regulations require duty holders to have a written plan for managing any asbestos-containing materials that are not immediately removed.
5. Ensure contractors are informed. Anyone carrying out work on the property must be made aware of any asbestos-containing materials before they begin. This is a legal obligation, not a courtesy.
6. Review the register regularly. Asbestos-containing materials can deteriorate over time. Regular monitoring and periodic re-surveys are essential to maintaining an accurate picture of risk.

Failing to take these steps is not just a regulatory breach — in the context of shipbuilding’s history, it is a failure to learn from one of the most costly industrial mistakes this country has ever made.

Frequently Asked Questions

Why was asbestos so widely used in shipbuilding?

Asbestos was valued in shipbuilding for its exceptional fire resistance, durability in harsh maritime conditions, and low cost. It could be applied in many forms — as lagging, boards, spray coatings, and gaskets — making it suitable for virtually every part of a vessel. At the time of its peak use, the health risks were either unknown to workers or actively concealed by manufacturers and employers.

Which diseases are most commonly linked to shipyard asbestos exposure?

The primary diseases associated with shipyard asbestos exposure are mesothelioma, asbestosis, lung cancer, and pleural disease including pleural plaques and diffuse pleural thickening. Mesothelioma — a cancer almost exclusively caused by asbestos — is particularly prevalent in communities with a strong shipbuilding heritage, such as Barrow-in-Furness, Birkenhead, and Govan.

Can family members of shipyard workers also be at risk?

Yes. Secondary or para-occupational exposure is well documented. Asbestos fibres were carried home on workers’ clothing and skin, exposing household members — particularly those who handled or laundered contaminated workwear. Some family members have subsequently developed mesothelioma and other asbestos-related diseases as a result of this indirect exposure.

Do the Control of Asbestos Regulations apply to ships and maritime facilities?

Yes. The Control of Asbestos Regulations apply to any workplace or structure where asbestos may be present, including vessels, dry docks, port facilities, and dockside buildings. Duty holders responsible for such properties are legally required to identify asbestos-containing materials, assess their condition, and manage the risk in accordance with HSE guidance, including HSG264.

What should I do if I suspect asbestos is present in a historic vessel or waterfront building?

Do not disturb any materials you suspect may contain asbestos. Commission a professional asbestos survey from a qualified surveyor accredited to carry out assessments in line with HSG264. For properties in active use, a management survey is typically the starting point. If refurbishment or demolition is planned, a more intrusive demolition survey will be required before any work begins.

Asbestos in Ships: What Every Worker, Owner and Surveyor Needs to Know

Asbestos in ships remains one of the most serious and persistent occupational health hazards in the maritime industry. Whether you work in a shipyard, manage a vessel, or oversee a commercial fleet, understanding where asbestos hides, how exposure happens, and what UK law requires is not optional — it is essential.

The consequences of getting it wrong can be fatal, and they can take decades to appear. This post covers the materials involved, the health risks, the legal framework, and the practical steps needed to protect workers and comply with regulations.

Why Ships Are Such a High-Risk Environment for Asbestos

Ships built before the mid-1980s were constructed during an era when asbestos was considered the ideal building material. It was cheap, abundant, fire-resistant, and highly effective as insulation — all qualities that made it attractive to naval architects and shipbuilders alike.

Asbestos was used extensively throughout vessels of all types: commercial cargo ships, passenger liners, tankers, and Royal Navy warships. The quantity used was staggering. Commercial ships could contain several tonnes of asbestos-containing materials (ACMs), while larger naval vessels held considerably more.

Even today, vessels built before the mid-1980s that remain in service, are being repaired, broken up, or decommissioned still contain significant amounts of ACMs. The risk has not gone away — it has simply shifted from new construction to maintenance, refurbishment, and ship breaking.

Where Asbestos Is Found in Ships

Asbestos was used in virtually every part of a ship where fire resistance, insulation, or durability was required. If you are working on or surveying an older vessel, assume ACMs are present until a proper survey confirms otherwise.

Insulation and Thermal Systems

Boilers, steam pipes, and engine room insulation were among the heaviest users of asbestos in ships. Lagging — the insulation material wrapped around pipes and boilers — was almost universally made from asbestos until safer alternatives became available. This lagging degrades over time, releasing fibres into the air.

Engine rooms are therefore among the most hazardous areas on any older vessel. Heat, vibration, and constant maintenance activity all accelerate the deterioration of ACMs in these spaces.

Structural and Decorative Materials

Asbestos was incorporated into a wide range of structural and finishing materials throughout a vessel’s interior. Many of these materials are not immediately visible — they sit behind panels, beneath flooring, or inside equipment casings.

Common locations include:

• Deck tiles and floor coverings
• Bulkhead (wall) panels and ceiling tiles
• Fire doors and fire-resistant partitions
• Gaskets and packing materials
• Rope and textiles used in electrical systems
• Spray coatings applied to structural steel
• Adhesives and mastics used in fitting out
• Paint and coatings on certain surfaces

This is precisely why a thorough management survey is the only reliable way to establish what is present before any maintenance or routine work begins on an older vessel.

Mechanical and Electrical Components

Pumps, valves, and gaskets throughout a vessel’s mechanical systems frequently contained asbestos. Electrical cables were often wrapped in asbestos-based fireproof materials, and hydraulic systems used ACMs in older ships as a matter of course.

These components require regular maintenance, which means workers are repeatedly exposed to potentially disturbed ACMs during routine servicing — not just during major overhauls. This is one of the most underappreciated exposure routes in the maritime sector.

How Shipyard Workers and Crew Are Exposed to Asbestos

Exposure to asbestos in ships does not only happen during dramatic demolition work. It occurs during everyday maintenance tasks, in confined spaces where fibres accumulate, and sometimes without workers realising the materials they are handling contain asbestos at all.

Direct Exposure During Repair and Maintenance

Cutting, drilling, grinding, or disturbing any ACM releases microscopic fibres into the air. In the confined spaces below deck — engine rooms, boiler rooms, cable runs — ventilation is poor and fibre concentrations can reach dangerous levels quickly.

Workers carrying out what appear to be simple jobs — replacing a gasket, re-lagging a pipe, or cutting through a bulkhead — can receive significant asbestos exposure if ACMs are present and the work is not properly controlled. The confined nature of shipboard spaces makes this risk particularly acute.

Secondhand and Environmental Exposure

Asbestos fibres are microscopic and cling to clothing, hair, and skin. Workers who handle ACMs can carry fibres home, exposing family members through what is known as secondary or domestic exposure. This has caused serious illness in the relatives of shipyard workers and naval personnel.

In large shipyards, fibres released in one area can travel through ventilation systems or on air currents to affect workers in adjacent spaces who are not directly involved in the disturbing work.

Ship Breaking and Decommissioning

The breaking up of older vessels is one of the highest-risk activities in the maritime industry. When a ship is dismantled, ACMs that have been undisturbed for decades are suddenly exposed, cut, and removed. Without rigorous controls, fibre levels in ship breaking yards can be extremely high.

Under the Control of Asbestos Regulations, strict duties are placed on anyone responsible for work that disturbs asbestos, and ship breaking is no exception. Licensed asbestos contractors must be used for the removal of the most hazardous ACMs, including pipe lagging and spray coatings.

Before any significant dismantling work begins, a full demolition survey must be completed. This is a legal requirement, not a recommendation, and it must be intrusive enough to access all areas of the vessel.

The Health Risks of Asbestos Exposure in the Maritime Industry

The diseases caused by asbestos exposure are serious, progressive, and in many cases fatal. What makes them particularly insidious is the latency period — the time between exposure and the appearance of symptoms can be anywhere from 20 to 50 years or more.

Mesothelioma

Mesothelioma is a cancer of the lining of the lungs, abdomen, or heart that is almost exclusively caused by asbestos exposure. It is aggressive, has a poor prognosis, and cannot be cured in most cases.

Shipyard workers and naval veterans are disproportionately represented among those diagnosed with mesothelioma in the UK. The long latency period means that people working in shipyards in the 1960s and 1970s are still being diagnosed today. The disease does not discriminate between those who worked directly with ACMs and those who were simply present in areas where asbestos was being disturbed.

Asbestosis and Pleural Disease

Asbestosis is a chronic scarring of the lung tissue caused by the inhalation of asbestos fibres over time. It causes progressive breathlessness, a persistent cough, and chest tightness. There is no treatment that reverses the damage — management focuses on slowing progression and improving quality of life.

Pleural thickening and pleural plaques are also common among those with significant asbestos exposure. While pleural plaques are not themselves disabling, they are a marker of exposure and can cause discomfort. Both conditions are recognised under UK occupational disease law.

Lung Cancer and Other Cancers

Asbestos exposure significantly increases the risk of lung cancer, particularly in those who also smoke. It has also been linked to cancers of the larynx, ovary, and gastrointestinal tract.

Symptoms of asbestos-related disease — including persistent cough, unexplained weight loss, chest pain, and shortness of breath — should always be investigated promptly by a GP, particularly in anyone with a history of working in shipyards or on older vessels.

UK Legal Framework: What the Regulations Require

In the UK, the management and removal of asbestos is governed primarily by the Control of Asbestos Regulations and associated HSE guidance documents, including HSG264 for asbestos surveys. These regulations apply to all workplaces, including vessels under UK jurisdiction.

The Duty to Manage

Anyone responsible for a non-domestic premises — including a vessel used for commercial purposes — has a duty to manage asbestos. This means identifying whether ACMs are present, assessing their condition and risk, and putting in place a management plan to prevent exposure.

For ships and maritime facilities, this duty applies to the owners and operators of vessels, as well as to those responsible for shipyard buildings and dry dock facilities. Ignorance of the regulations is not a defence.

Asbestos Surveys for Vessels and Maritime Premises

HSG264 sets out the two main types of asbestos survey. A management survey identifies ACMs that may be disturbed during normal use and maintenance, while a demolition survey is required before any significant work that will disturb the fabric of a building or vessel.

For a ship undergoing refurbishment or decommissioning, a full refurbishment and demolition survey is essential before work begins. This survey must be intrusive — accessing all areas, including those behind panels and within equipment — to ensure nothing is missed.

Supernova Asbestos Surveys carries out surveys across the UK, including at port facilities and maritime premises. Whether you need an asbestos survey London for a vessel or dock facility, our team can advise on the right survey type and deliver a thorough, HSG264-compliant report.

Licensed Removal and Notifiable Non-Licensed Work

The Control of Asbestos Regulations distinguishes between licensed work — which must be carried out by a contractor holding a licence from the HSE — and notifiable non-licensed work (NNLW). Pipe lagging, spray coatings, and loose asbestos insulation all fall into the licensed category.

Before any asbestos removal work begins on a vessel, the type of ACM must be identified and the appropriate contractor engaged. Attempting to remove licensed materials without the correct authorisation is a criminal offence and puts workers at serious risk.

Protective Measures for Workers in Shipyards and on Vessels

Where asbestos is present and work must be carried out, proper controls are non-negotiable. The hierarchy of control under UK health and safety law requires that exposure is eliminated where possible, and where it cannot be eliminated, it must be reduced to the lowest reasonably practicable level.

Personal Protective Equipment

Workers disturbing ACMs must wear appropriate respiratory protective equipment (RPE) — typically a half-face or full-face respirator with a P3 filter, or a powered air-purifying respirator. Disposable coveralls, gloves, and boot covers must also be worn to prevent fibres being carried out of the work area.

RPE must be correctly fitted and face-fit tested to be effective. A mask that does not seal properly provides little protection. Employers are legally required to ensure workers are trained in the correct use, fitting, and disposal of PPE.

Controlled Work Areas and Air Monitoring

Licensed asbestos removal work must be carried out within a controlled enclosure, with negative pressure ventilation to prevent fibres escaping. Air monitoring must be conducted during and after the work to confirm that fibre levels are within acceptable limits before the area is cleared for re-occupation.

Records of air monitoring, waste disposal, and the work itself must be retained. Under the Control of Asbestos Regulations, employers must keep records of workers’ exposure to asbestos for a minimum of 40 years.

Training and Information

Anyone who is liable to disturb asbestos in the course of their work must receive appropriate asbestos awareness training. For workers carrying out licensed removal, additional specific training is required. Employers have a legal duty to provide this training and to ensure it is kept up to date.

In shipyards and on vessels, this means that maintenance engineers, electricians, pipe fitters, and anyone else working on older ships must be trained before they pick up a tool. Asbestos awareness training is not a one-off box-ticking exercise — it must be refreshed regularly and be relevant to the actual tasks workers perform.

Practical Steps for Vessel Owners, Fleet Managers and Shipyard Operators

If you are responsible for a vessel or maritime facility built before the mid-1980s, the following steps are not optional. They are the baseline of legal compliance and worker protection.

1. Commission an asbestos survey. If no survey has been carried out, or if records are incomplete, arrange a survey immediately. For vessels in active service, a management survey establishes what is present and where. For vessels about to undergo significant work, a refurbishment and demolition survey is required.
2. Create and maintain an asbestos register. The survey report forms the basis of your asbestos register. This document must be kept up to date, accessible to anyone who might disturb ACMs, and reviewed regularly.
3. Implement a written management plan. The duty to manage requires not just identification but action. Your management plan should set out how ACMs will be monitored, who is responsible, and what controls are in place.
4. Engage licensed contractors for high-risk work. Never attempt to remove pipe lagging, spray coatings, or other high-risk ACMs without a licensed contractor. The cost of doing this properly is vastly lower than the cost of enforcement action, civil liability, or the human cost of preventable disease.
5. Train your workforce. Ensure all relevant workers have up-to-date asbestos awareness training. Keep records of training completed.
6. Review before any planned maintenance or refurbishment. Before any work begins on an older vessel, check the asbestos register and, if the work is intrusive, commission a further survey if necessary.

Frequently Asked Questions

Is asbestos still present in ships today?

Yes. Any vessel built before the mid-1980s is likely to contain asbestos-containing materials. Many of these ships remain in service, are undergoing maintenance, or are being decommissioned. The presence of asbestos does not automatically make a vessel unsafe, but it must be identified, managed, and controlled in accordance with the Control of Asbestos Regulations.

Do the Control of Asbestos Regulations apply to ships?

Yes. The Control of Asbestos Regulations apply to all workplaces under UK jurisdiction, including commercial vessels. Owners and operators of vessels have a duty to manage asbestos just as the owner or manager of any other non-domestic premises would. Failure to comply can result in enforcement action by the HSE and significant civil liability.

What type of asbestos survey does a ship need?

This depends on what work is planned. For vessels in active service where only routine maintenance is being carried out, a management survey is the appropriate starting point. For any vessel undergoing significant refurbishment, conversion, or decommissioning, a full refurbishment and demolition survey is required before work begins. HSG264 sets out the standards that both survey types must meet.

Who can remove asbestos from a ship?

The type of contractor required depends on the category of ACM involved. High-risk materials — including pipe lagging, spray coatings, and loose asbestos insulation — must be removed by a contractor holding a current HSE licence. Other materials may fall into the notifiable non-licensed work category, which still requires notification to the relevant enforcing authority and adherence to strict controls. Never attempt to remove any ACM without first establishing its category through a proper survey.

What are the symptoms of asbestos-related disease?

Asbestos-related diseases typically have a latency period of 20 to 50 years, meaning symptoms may not appear until decades after exposure. Warning signs include persistent breathlessness, a chronic cough, chest tightness or pain, and unexplained weight loss. Anyone with a history of working in shipyards or on older vessels who experiences these symptoms should seek medical advice promptly and inform their GP of their occupational history.
